Electric vehicle roundup: 1) Fisker taps former GM chief marketing officer Joel Ewanick to be its new chief commercial officer. 2) General Motors (GM-0.6%) will debut an all-electric version of the Chevrolet Spark at the L.A. Auto Show this week. 3) The Mercedes Benz (DDAIF.PK) B-Class Electric Drive is slated to hit North America in 2014 after recording solid demand and interest abroad. The model utilizes the battery from the Tesla (TSLA-1.5%) Model S.

My 1984 Toyota Celica GT got 37 MPG at 137,000 miles at the time it was stolen in 1994. For the life of me, I can't understand how/why I'm supposed to get excited about an ugly, tiny "green" car made 30 years later that gets 38 mpg. And is made of plastic.

First of all the cars that were damaged by hurricane Sandy were made by Fisker not Tesla, secondly it was not the batteries but a short in the conventional electronic systems that caused a fire. If you criticize electric cars, at least know what you are talking about.

I predict the future of the automobile to be electric propulsion and battery power. While the Tesla model S has proven the concept, batteries with higher energy density will come along as the market develops. The recharging infrastructure will also develop with the market. Everything from rising tides, falling water, solar, wind, and fossil fuels will be used to make that electricity.

The first 50 years of electronics was based on the vacuum tube and led to radio, color television, and infant computers. Fifty years ago the transistor showed promise but lacked performance. But today, who uses vacuum tubes?
